Class FileFilter

FileFilter is an abstract class used by JFileChooser
for filtering the set of files shown to the user. See
FileNameExtensionFilter for an implementation that filters using
the file name extension.

A FileFilter
can be set on a JFileChooser to
keep unwanted files from appearing in the directory listing.
For an example implementation of a simple file filter, see
yourJDK/demo/jfc/FileChooserDemo/ExampleFileFilter.java.

How to Use File Choosers,
a section in The Java Tutorial.
